Beit known that l, Humeur H. Fem', a citizen of the United States, residing at Chicago, in the county oit @ook and tritate oi' Illinois, have invented a certain new and useful improvement in Aut-omobilc-lflorns, ot' which the 'following a full, clear, couh'ad to the accompanying drawings, :torn'nngli a part of this specilication.

My invention relates to automobile horns trically operated horn 'which is etlicient and manufactured.

The horn of my invention can, iii' desirethbe connected with a source o't` ignition current Jfor the automobile with which itis associa-ted or, if desired, it may receive its operating current from batteries provided lfor tbatpurpose.y

The automobile horn shown in the drawings is particularly adapted to receive its operatingcurrent from an. alternating current ignition magneto although l wish it to be understood'that its use is not so limited, as by provision o'l an extremely simple circuit breaking' arrangement my horn is adafited Simplicity is a feature of my horn construction. The parte are such that sheet My invention will be more clearly understood by' referring 'to the accompanying drawings 'forming part ot this speciiication,

without departing from my invention. Se cured to'and carried by the cylinder 5 is the eupshaped member G. This member 6 and a plate 7 'forni the diaphragm chamber 8. Scrjrurcd between the member 6 and the plate 7 is the sounding diaphragm. 9. Suitable packing or insulation 10 .may be disposed on one or both sides of the diaphragm 9V if desired. The cup-shaped member 6, the plate 7. the diaphragm 9, and the packing l() are securely held in position by means ol a plruality ol screws 11. Any suitable means indicated at 12 may be provided for securing the horn to the automobile. The end closure for the diaphragm chamber is indicated at 13. Between the end closure 13 and the plate 7 there is interposed the. spring'diaphragm 14. The endclosure. and the spring diaphragm are secured by means The end to receive the end olf a coil housingr lor bell magnet 17. lVithin the housing 17 there is disposed the bell magnet-coil 18. Thefcoil 18is mounted on a-spool 20 between the liber disks 19 and 19. A tube 9.0 extends through the disks 19 and-'i9'. coil 1S, and apertures in the housing i7 and the end closure 13. The tube 2O 4which is spread 'or riveted inside the closure 1?, as shown, is provided with a shoulder' '21. lo engage the disk 19. It will thus be seen that by a simple arrangement, the housing 17 and the parts carried thereby are se.

curely'hcld in position. A striking rod 22 which extends through the tube 2O passes thrmigh und .is secured to the spring diaphragm 1st by means of nuts 25 and 26. A,

nut or nuts 27 may be provided to weight the end of the, striking rod if necessary or desired. The other end of the striking rod carries an adjustable armature 28. A nut 29 may be provided to lock the armature at any desired position relatively to said striking rod. Within thetube 20 is disposed' a short piecc'o'lf tubing 30 which serves to vcenter the strikina' rod 29. and so prevent it from engaging tile louter endo'f the tube 20.. The ends ol the coil 18 are secured toterminals l Ihave shown a block 33 carryingconductors 34: and 34 as a convenient means 'for connecting thetcoil with the source oi current. The cap lits over the housing 17 and conceals and protects the armature E28. The screw 36, which the sounding diaphragm 9. It should be noted that the space between the striking rod 22 and the screw 36 may be readily adjusted to suit any requirement-s. v

In the diagrammatic .representation of an automobile power plant and electrical con-l nections shown in Fig. 4, an ordinary multiple cylinder internal combustion engine is shown at 38 and the alternator housing at 39. need not here describe the ignition circuit. It will suiiice to say that suitable means is provided for directing current to the spark gaps in the engine cylinders The terminal 31 of the horn is connected to the insulated ter minal 40 and the terminal 32 is electrically connected to the alternator housing 39.

The operation of the horn is as follows:

When Vcurrent is directed through coil 18A by pressing the push button 41, the armature 28 is drawn toward coil- 18, thrusting the striking rod 22 into engagement with the end 4oi' screw 86 carried by the sounding diaphragm 9. When the current reverses, vthe armature is thrust away from thecoil by the'spring diaphragm 14 and again attracted. Every time the armature is attractedl the striking rod 22 engages vthe screw 36, thereby causing the sounding diaphragm 9 to vibrate and set sound waves in motion. If the sounding diaphragm is held rigidly in place andthe moving parts of the horn properly adjusted, a very good tone is produced. The push button 41 is preferably carried by the steering column of the automobile.

In the modified form of horn construction shown in Fig. 3, one end of the coil within the coil housing 42 is connected to the terminal 43. lThe other end is electrically connected to the striking rod 44 which carries an armature 45. The contact spring 46 carried by the diaphragm chamber end closure 47 carries the adjusting screw 48 which is disposed concentric to the striking rod 44. The rod 44 and the screw 48 prefvis as follows: lVhen current is directed v. through the bell coil within the housing 42,

the' armature 45 is attracted toward the coil opening the circuit at the point where the striking rod 44 engages the screw 48. The

coil being denergized, the rod 44 is thrown into engagement with the screw 48, whereupon the flow of current through the coil is restablished and the armature re-attracted.

While I have shown the spring -support-14 tion.' therefor. The diaphragm is, however, the preferred form of spring.

While I have illustrated my horn in .the Y particular .embodiments herein shown and described, I do not, however, limit myself to these constructions but may employ any equivalents that might suggest themselves to those skilled in the art.

I claim as new and desire to secure by Letters Patent:

2. In combination, an alternating current generator, a horn comprising an electro# magnet, an amplifying device, a sounding diaphragm disposed between said elect-romagnet and said amplifying device, said electromagnet being connected across the rterminals of said alternating current generator, a movable armature for said electromagnet arranged to be 'actuated by said electromagnet when the latter is energized, and a spring diaphragm connected with the armature arranged to normally hold othe latter out of engagement with the sounding diaphragm, lsaid armature adapted to vibrate between points on opposite sides of its normal position,
